1 Introduction

SUSI – A Bridge to Simplify & Enhance H/W & Application Implementation Efficiency

When developers want to write an application that involves hardware access, they have to study the specifications to write the drivers. This is a time-consuming job and requires lots of expertise.

Advantech has done all the hard work for our customers with the release of a suite of Software APIs (Application Programming Interfaces), called Secured & Unified Smart Interface (SUSI).

SUSI provides not only the underlying drivers required but also a rich set of user-friendly, intelligent and integrated interfaces, which speeds development, enhances security and offers add-on value for Advantech platforms. SUSI plays the role of catalyst between developer and solution, and makes Advantech embedded platforms easier and simpler to adopt and operate with customer applications.

 

1.1 Functions

1.1.1 GPIO

[[File:]]

General Purpose Input/Output is a flexible parallel interface that allows a variety of custom connections. It supports various Digital I/O devices – input devices like buttons, switches; output devices such as cash drawers, LED lights…etc. And, allows users to monitor the level of signal input or set the output status to switch on/off the device. Our APIs also provided Programmable GPIO and allows developers to dynamically set the GPIO input or output status.

1.1.1 SMBus

[[File:]]

SMBus is the System Management Bus defined by Intel® Corporation in 1995. It is used in personal computers and servers for low-speed system management communications. Today, SMBus is used in all types of embedded systems. The SMBus APIs allows a developer to interface a platform to a downstream embedded system environment and transfer serial messages using the SMBus protocols, allowing multiple simultaneous device control.
